Legion, that's incorrect. Opening a Hellgate wasn't a feat that required a unique connection. The hellgate literally had a "key hole" for the sword. The user above is correct. It's a magic sword. No one but Sparda's offspings/descendants has ever used it to a great mastery. I don't see them using the powerful techniques that slashes people to bits.
